In order to practice my skills, I happened to need to make a sidebar when I was learning to type a website. I also checked various plug-ins and frameworks on the Internet to achieve this function, but I wanted to learn to use js natively. After giving it a try, I briefly completed the implementation of the sidebar, which can be used as a reference for beginners, but the coding ability is limitedUse js to write responsive sidebar examples.

The main design is the animate() function. The animate() method performs custom animations of CSS property sets. This method changes an element from one state to another through CSS styles. CSS property values ​​change gradually, allowing you to create animated effects. Only numeric values ​​can be animated (e.g. "margin:30px"). String values ​​cannot be animated (such as "background-color:red"). Please search for more information by yourself, I will not introduce it in detail. In addition, the media query method is used to adjust the size design of the sidebar by detecting the screen size of the current device. The media query method can set different styles for different screen sizes, especially if you need to design a responsive page.


#The following is the specific implementation, with the code attached:

##

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width,initial-scale=1"/>
	<title>侧边栏</title>
	<link  href="css/sideBar.css" rel="stylesheet" type="text/css" />
</head>
<body>
	<p class="container">
		<p class="header">
			<p class="nav-icon">
				<span></span>
				<span></span>
				<span></span>
			</p>
		</p>
		<p class="content">侧边栏内容</p>
		<p class="sideBar">
			<p class="sideBar-left">
				<p class="pider"></p>
				<p class="body-content">

	$(".sideBar-left").height(windowHeight);
	$(".sideBar-right").height(windowHeight);
	//侧边栏由左向右滑动
	$(".nav-icon").on("click",function(){
		$(".sideBar").animate({left: "0"},350);
	});
	//点击退出,侧边栏由右向左滑动
	$(".exit").on("click",function(){
		$(".sideBar").animate({left: "-100%"},350);
	});

})
